Running Open Cl implementation for Sobel on CPU

[sraha]

Hello,

I followed Intel tutorial on the following link:

https://software.intel.com/en-us/INDE-OpenCL-Sobel ( run Sobel using OpenCl )

It ran successfully on GPU. However, when I changed the command line arguments from GPU to CPU and also changed the device to CPU, it didn't work. I got the following error: 

Error 1 error MSB3721: The command ""C:\Intel\OpenCL\sdk\bin\x86\ioc32.exe" -cmd=build -input=".......Visual Studio 2013\Projects\Sobel_OCL\SobelKernels.cl" -output="Debug\SobelKernels.out" -VS -device=CPU -simd=default -targetos=current            -bo="           "" exited with code -1073741819. C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\BuildCustomizations\IntelOpenCL.targets 98 5 Sobel_OCL.

Although the usage of this program says: " Usage: Sobel [num test iterations] [cpu|gpu] [intel|amd|nvidia] [SurfWidth(^2 only)] [SurfHeight(^2 only)] [show_CL | no_show_CL".

What should I do to run the code on CPU only? knowing that I installed CPU only runtime for OpenCL.

Any help and suggestion are highly appreciated.

Thanks,

Samah

SamahR,

Can you explain what you changed exactly where? I don't follow... Was it at project level?

If you're on a system with Intel® Graphics and have it's driver package installed... that should come with both CPU and Intel Graphics OpenCL implementations. ioc64 or ioc32 should serve as pass through to the respective Intel implementations when -device= is used.

Can you execute the offline compiler front end command in the error listed by hand? That might provide some hints. Perhaps the install paths are different. Could be many things.
